The Stranger In Slytherin

Hogwarts, Sixth Year. Jessica Lightning Mikcloud has spent most of her time at the castle unnoticed, excelling in her studies while keeping her greatest secret hidden-her ability to speak Parseltongue. With only whispers of her Gaunt heritage, she has nearly broken Tom Riddle's academic records, all while questioning how such brilliance could lead to darkness.
But this year, something shifts. The Vanishing Cabinet, long forgotten, stirs with ancient magic. Unbeknownst to anyone, Lord Voldemort has devised a chilling plan-using his own preserved blood and Polyjuice Potion to walk the halls of Hogwarts once more, disguised as his sixteen-year-old self.
When he steps out of the cabinet in the Room of Hidden Things, feeling triumphant at his silent infiltration, he hears something unexpected-soft, beautiful humming. Drawn to the sound, he finds a girl sitting in a plush pillow fort of black and green crushed velvet, reading with serene elegance. She is unfamiliar yet captivating, and for the first time in decades, something inside him hesitates.
As Hogwarts carries on, untouched by the war brewing outside, secrets begin to unravel. What happens when the brightest student of the present unknowingly catches the eye of the ghost of the past? And will Jessica's hidden ties to Slytherin's bloodline be the key to uncovering the truth... or sealing her fate?
